“…Some marine toxins have been associated with seaweed such as palytoxin (PTX), domoic acid (DA) and analogs, ciguatoxins, and cyclic imines (CIs). PTX is structurally complex and an extremely potent marine toxin (Beletskaya, Collins, & Murray, ). It is associated with a Hawaiian legend called “limu‐make‐o‐Hana” meaning “seaweed of death from Hana.” Studies later revealed that the samples from the Hana tide pool were not of seaweed, but of a soft coral ( Palythoa toxica ) (Ciminiello, Dell'Aversano, & Forino, ).…”

According to Wang (), PTX has later been found in other organisms such as seaweeds and shellfish (Beletskaya et al., ). For example, Rhodes, Adamson, Suzuki, Briggs, and Garthwaite () reported that Ostreopsis (a dinoflagellate known for toxic algal blooms) has shown to occur epiphytically on seaweeds in New Zealand and is of a concern because it produces PTX and its analogs.…”

“…A recent study described six novel biosynthetic intermediates of DA in C. armata (Maeno et al, 2018). DA ingestion was previously reported after three Japanese children ingested 20 mg extracts of the aforementioned red seaweed (0.04 to 0.8 mg/kg bw) without apparent effects (Beletskaya et al, 2015). Also, kainic acid is an amino acid found in some types of red seaweeds such as P. palmata (Jørgensen & Olesen, 2018).…”

Seaweed is a source of protein that can help overcome the anticipated challenges of a growing world population and the current challenges for finding alternatives for animal proteins in the Western diet. Thus far, data on the safety of seaweed for feed and food purposes in the Western world are scattered. This study aimed to review the available knowledge on the presence of food safety hazards in seaweed, including factors influencing their presence, and to prioritize the hazards that may pose a risk to human health. Given current knowledge from the literature, data from the Rapid Alert System for Food and Feed, and results from a stakeholder survey, 22 food safety hazards were ranked into major (4), moderate (5), and minor (13) hazards. Arsenic, cadmium, iodine, and Salmonella were identified as major hazards. Hazards, where data gaps exist, should be carefully assessed. These include pesticide residues, dioxins and polychlorinated biphenyls, brominated flame retardants, polycyclic aromatic hydrocarbons, pharmaceuticals, marine biotoxins, allergens, micro‐ and nanoplastics, other pathogenic bacteria, norovirus, and hepatitis E virus. It is recommended to collect more data on these hazards in future studies. Many factors can affect the presence of hazards including seaweed type, physiology, season, harvest and cultivation environment, geography including the location of cultivation, alongside further processing. Moreover, when seaweed is cultivated near industrialized or anthropogenic activities, these activities may negatively influence water quality, which can increase the likelihood of hazards in seaweed. Results of the ranking prioritized hazards can be used to prioritize monitoring programs and adjusted given future additional knowledge covering the data gaps.
